iOS 11 beta 5 was launched by the company Apple Lossless Audio CODEC (ALAC), for iPhone and iPad, since last night developers and users can install the operating system update. Unfortunately, iOS 11 beta 5 is not really the best beta version ever released by the Apple company for iPhone and iPad, so you have to be careful.
It was expected that iOS 11 beta 5 would not run smoothly on iPhone or iPad, and this turns out to be true, as you can see. The performance of iOS 11 beta 5 compared to that of iOS 10.3.3 is bad, many blockages exist in the daily use of iPhone or iPad terminals with the new version of the operating system.
For the iPhone 5S, we are talking about a serious regression in performance on iOS 11 beta 5 compared to iOS 10.3.3, so if you are thinking about installing it, you know what to expect. The iPhone 5S will have iOS 11 as the last major version for which Apple will provide updates, so it is normal that its performance is not even among the best.
Of course, if iOS 11 beta 5 has poor performance on the iPhone 5S now, this does not mean that things will be the same in the final version, as Apple can modify the performance until then. In general, the first beta versions of an operating system offer the worst performance, but things change until the final version is released, and the same thing will happen with iOS 11.
